VEHICLE ARRESTING SYSTEM

STUDY WAS CONDUCTED TO DEVELOP AN ARRESTING SYSTEM FOR SNAGGING A VEHICLE LEAVING THE ROADWAY NEAR FIXED HIGHWAY OBSTACLES. ATTENUATOR DESIGNS, HOOK DESIGNS AND SYSTEM CONFIGURATION LAYOUTS FOR BOTH THE SYSTEM AND VEHICLE WERE STUDIED. DATA WERE COMPILED OF VEHICLE DATA AND UNDER- CARRIAGE STRUCTURAL ANALYSIS. PRESENT DAY VEHICLES CANNOT WITHSTAND DECELERATION FORCES OF 12G APPLIED THROUGH A SINGLE HOOK WITHOUT SUBSTANTIAL MODIFICATION. AN ALTERNATE METHOD OF ENGAGING THE VEHICLE TO THE HYDRAULIC ATTENUATOR DESIGN WAS DEVELOPED. A FULL SCALE HARDWARE TEST WAS CONDUCTED TO CONFIRM THE VALIDITY OF THE STRUCTURAL ANALYSIS. TESTS CONDUCTED FULLY CONFIRMED THE ANALYSIS. THE FOLLOWING WERE SYSTEM APPROACHES: (1) THE FENCE BARRIER, AND (2) THE ONE-WAY GUARD RAIL. CRASH TEST RESULTS ON THE ONE- WAY GUARD RAIL ARE REPORTED. TEST RESULTS ARE PRESENTED IN THE FOLLOWING THREE BASIC PHASES: (1) ORIGINAL CONCEPTUAL STUDIES OF VEHICLE ARRESTING SYSTEMS, (2) ALTERNATE CONCEPTUAL STUDIES OF VEHICLE ARRESTING SYSTEMS, AND (3) ONE-WAY GUARD RAIL CONCEPT.
